The right tennis string tension can make a racquet feel controlled and steady—or lively and comfortable. If your shots are landing long, your arm feels sore, or the ball seems to fly off the strings, a small tension change may help.
Use the tennis string tension chart below as a starting point, not a rule. The best setting depends on your string type, racquet, swing, and playing style. Change tension in small steps, then give yourself a few sessions to judge the result.
Tennis String Tension Chart
These ranges suit many adult players using a standard 98–100 square-inch racquet. Check the tension range printed on your racquet or listed by its manufacturer before stringing. If its recommended range differs, stay within that range.
| String or setup | Starting tension | Often suits |
|---|---|---|
| Multifilament, full bed | 50–54 lb (23–24.5 kg) | Comfort, touch, and a lively response |
| Synthetic gut, full bed | 50–55 lb (23–25 kg) | All-around play at a moderate price |
| Natural gut, full bed | 52–56 lb (23.5–25.5 kg) | Comfort, power, and feel |
| Polyester, full bed | 44–48 lb (20–22 kg) | Players with fast swings who want control and spin |
| Hybrid: polyester mains, softer crosses | Polyester 46–50 lb; crosses 50–54 lb (21–23 kg; 23–24.5 kg) | A blend of control and comfort |
Those are practical starting points, not guaranteed outcomes. A bigger racquet head or open string pattern may feel livelier than a smaller, denser one at the same tension. Two strings pulled to 50 pounds can also feel quite different because materials and construction affect how the stringbed responds.
How to Choose Your Starting Tension
For more control
If the ball tends to sail long, try increasing tension by 2 pounds (about 1 kg). A firmer stringbed can feel more predictable, though it may also feel less lively. Before making a large change, check your contact point and aim: late contact or a rushed swing can send shots long regardless of tension.
For more comfort and depth
If your racquet feels harsh or you struggle to get depth, reduce tension by 2 pounds. A lower setting often gives the ball a livelier response and can feel more comfortable, especially with multifilament or natural gut. Lower tension does not automatically mean more spin; technique and string movement matter too.
For polyester strings
Polyester can suit a player who swings fast and wants a controlled response, but it is typically firmer than multifilament or natural gut. Start lower than you would with a softer string—often around 44–48 pounds for a full bed—and replace it when it feels dead. If you are a beginner, have arm discomfort, or play with a compact swing, a softer string or hybrid may be a better first choice.
For hybrids
A common setup puts polyester in the mains, which run from the handle to the top of the racquet, and a softer string in the crosses. Many players start the crosses 2–4 pounds higher than the polyester mains, but follow your stringer’s advice and keep the setup within your frame’s recommended range. The result depends on the specific strings, not just the tension numbers.
String Options and Useful Starting Points
These are well-known string choices, each with a different feel. The tensions below are sample starting points for a standard 98–100 square-inch racquet, not official settings for every player or frame.
| String | Type and feel | Sample starting point | Trade-off |
|---|---|---|---|
| Wilson NXT | Multifilament; soft and lively | 51–54 lb (23–24.5 kg) | Comfortable, but generally less durable than polyester |
| Tecnifibre X-One Biphase | Multifilament; powerful with a crisp feel | 50–54 lb (23–24.5 kg) | Good touch and comfort; can be costly for frequent restringers |
| Head Velocity MLT | Multifilament; fairly controlled for its category | 50–54 lb (23–24.5 kg) | A useful softer-string option, though feel is personal |
| Solinco Hyper-G | Polyester; shaped and firm-feeling | 44–48 lb (20–22 kg) | Popular with aggressive hitters, but not the softest choice for the arm |
| Luxilon ALU Power | Polyester; crisp, controlled response | 44–48 lb (20–22 kg) | Can feel excellent when fresh, but tension and feel change with use |
These suggestions are starting points rather than head-to-head test results. If you have a history of elbow, wrist, or shoulder pain, ask a qualified stringer about a softer setup and consider getting medical advice. Tension alone cannot guarantee comfort.
How to Test a Tension
- Write down your current setup. Note the string, tension, racquet, and how long you played with it.
- Change one thing at a time. Move by 2 pounds rather than switching string and tension together.
- Test real shots. Rally, serve, and hit with your usual spin before deciding whether the setup works.
- Pay attention over several sessions. A new stringbed can feel different from one that has been played in, and polyester may lose its crisp feel as it ages.
Ask your stringer whether a quoted number is for both mains and crosses or whether the hybrid uses separate tensions. Also check whether the frame has special stringing instructions. Keeping notes makes your next adjustment much more useful.
Frequently Asked Questions
What is a good tennis string tension for beginners?
A comfortable multifilament or synthetic gut setup around 50–54 pounds (23–24.5 kg) is a reasonable place to start for many standard racquets. Follow your frame’s recommended range and adjust based on how it feels.
Does lower string tension give you more power?
It can make the stringbed feel livelier and help some players get depth with less effort. The effect depends on the string, racquet, and swing, so try a small change rather than assuming lower tension will solve every control or power issue.
Should I use the same tension for polyester and multifilament?
Usually, it is worth starting lower with a full bed of polyester than with multifilament. Polyester tends to feel firmer, so copying a soft-string tension can make the racquet feel uncomfortable or overly stiff.
How often should I restring?
Restring when strings break, feel noticeably loose or dull, or no longer give you a reliable response. Players who hit often may need to restring more frequently. With polyester, pay attention to feel as well as breakage.
Final Thoughts
Start with the chart, respect your racquet’s tension range, and make changes in small steps. A comfortable string that matches your swing is more useful than chasing one “perfect” number. Keep a record of each setup, and you will soon know which tension helps you play with confidence.
